Framing under a toilet

My toilet drain lands in the middle of a joist. Having to cut the joist I am framing in headers between the 2 joist on either side. Can these headers be singles or do they need to be double headers. 2X10's 16" centers.

Thanks,
awg

For added peace of mind,and by only using an extra 5' of material, double up.
